To all whom t may 00a-cern.'

Be it knoivn that l, AsBJonN SoNsri-rAG-EN, a subject of the King of Norway.. residing in Essex7 England, have invented certain new and useful improvements in Machines for Folding Paper, of Which the following is a specification.

This invention relates to improvements in and relating to paper folding machines and it has for its object to provide a machine designed more particularly for folding paper to form dividing strips for use in packing chocolates and other sweetmeats, provision being `made whereby the Width of the folded paper may be varied as desired.

The strips, When folded, may be of l. or U shaped cross-sectional outline and provision is made for cutting same the desired length.

In order that the invention may be the better understood drawings are appended in. Which:-

Fig. l is a side vieiv of a machine according to this invention,

Fig. 5 is a longitudinal section taken upon line it A Fig. l,

Fig. 6 is an elevation of the machine as seen from the discharge or cutting` end,

Fig. '7 is an end vieiv as seen from the opposite end,

Fig. 8 is a longitudinal section on line X X Fig. l, 1

Fig. 9 is a. front vieiv showing more clearly the construction and arrangement of the cutting device.

Referring to t-he accompanying dra-Wings l indicates a table or bed supported upon a foot or pedestal 2X. Securedto the upper surface of table l are brackets supporting a spindle 2 upon vWhichis mounted a roller 3. The spindle 2 has secured to it at its inner end a disc 2a formed of or faced with some suitable material or composition adapted to provide a good @ripping surface for a second Wheel secured toashaft 5,provided With fast and loose pulleys and carried in bearings 6, said shaft being arranged at a right angle to spindle 2. rlhe spindle 2 is slidable in its bearings and it has at its outer end a recess in which is placed a steel ball engaging a recess in the end of a lever 7 pivotally mounted inv a bracket 8 disposed upon the side of the. table 1. 'ihe other end of lever 'l' has formed upon it a stud engaging the interior of one end of a coiled spring l0 the opposite end of said spring engaging a stud upon a hand lever l1 moving over a plate l2 in which are provided a series of holes arranged upon a curved line having as its centre the fulcrum of the lever ll the hand lever permitting the disc 2a to be engaged With the Wheel with varying degrees of pressur I a pin or other device being provided for securing the lever l1 in its adjusted position.

The Wheel l is also adjustable across the face of the disc 2a so that the speed of the roller 3, by which the paper is drawn through the machine, may be varied as desired.

Co-operating with the roller Sis a second roller 3a carried in a bracket 13 disposed upon the underside of table l in which an opening 13a is formed through which roller 3 projects. i

The bracket i3 comprises two side members having extending between them a part 13b perforated for the passage of a stud 14 by means of Which and nut l5 the said bracket is secured in position. ln order to adjust the pressure of roller 3 against roller 3a the bracket i3 at its outer end is prov'ded With a cross-member i6 of circular cross-sec tion, which part engages slots formed on the end of an inverted U-shaped bracket also secured to the undersurfice of table l. The bracket 13 is thus capable of a radial movement permitting' the aforesaid adjustment to be effected. Y

As alread;7 stated the driving friction disc l is adjustable across the face of the disc 2a and in order that this adjustment may be effected there is provided a screwed spindle l5 supported bv the aforementioned brackets and liaving at one end a milled head 15b. Mounted upon the spindle 15a is a substantially inverted U-shaped body 18 the limbs of which engage between collars formed upon the boss of disc si.. By this means when the spindle 15a is rotated in one or other direction a corresponding movement is imparted to disc 4 With the result that Vthe speed at which the paper is fed throughthe machine is retarded or eccellerated. Y Y

Y One ot the limbs ot the bodylS is eXtended to form a pointer 1S" and arranged ad-l prises two elements of which one ctnnprisesV` i a steel plate or blade2i) recessed intothe end of the'bed'l and ainovable element comprising` two arms 21 radiating from a central boss 29 secured to the driving shalt 5. VThe arms 21, at their upper ends, are provided with parts 2la extending therefrom ata right angle to the body of said'arms. The extensions 2l are provided upon each side with lugs 23 through which pass set-screws 24 provided with lock-nuts 25. A blade, indicated by 25, Yis mounted by means oli a screw 27 upon each extension of arms 21 the said sclrew passing Ltreelv through vthe blade and being screwed into the extension. The ylades are thus tree to pivot in the Vplane of their rotation upon the screws 27 Vtheir angular position beingy adjusted Aby means of the aforesaid set-screws so that they may be set to secure the most 4etliective cutting action. 2S indicates spring plates introduced between the heads of screws 2? and said blades v f Y 'lhepapen indicatedbv :nh is carriedby bolohin 29 supported on a spindleBO carried by horizontally disposed bracket 31 supported at one end' from the .vertical niember ot the pedestal. Thel bracketis slotted at32 tor the passage of the end spindle 30' which spindle is provided with a Yscrewthread engaging a nut whereb7 the position ot' the spindle longitudinally ot the bracket 3l may be varied as desined.V Projecting from the inner tace ol the bracket 31 is a lng` B1- bored for the passage' ot,Y a rod the lower end of which engages a hole or ojlI the pedestal said rodbeing secured in said socket by means ot a screw 36. Adjustably secured upon the rod 35 by means of a screw 37 isa boss 38 from the inner taceot which projects a stud passing through a slotr l0 in an arm il and b v means of which stud said arm isadjustabliv secured to said boss. ,The armll' at its outer end, carries a roller over which the paper passes being guided upon each side in its passage from the roll to the paper by walls or partitions disposed upon .each side o t the web. Extendingdownwardly .trom the outer endroit bracket l1 is a sheet metal plate or guide 3lIl so bent or formed that the paper, in moving;` thereover. has

Y

The body 5 2 is lprovided upon each side with extensions 5d between which the 4second body 53 is pivotally mounted upon a. spindle 55 being` secured against rotary movergient by means of the thumb-screw 56 passing; through one ot the extensions 54 and into an extension 57.11pon body 58. As the tolder is adjustable transverselyotV the line ot movement oft the' that bjr setting it over to one .side orv other the paper will be folded upon l its Vcentro line or to onefvside orthe other thereof so that the width otvthe respective folded portions may be varied asdesired.

The plate just referred to is turned overv` and inwards at i its inner end at' 60b the forward edge being rounded as shown and the edge contacting with the paper being inclined.V Secured in any convenient manner to the upper sur-A face ofthe plate 60 andv in spaced' relationship thereto is a second plate 6l havingl its inner end ot T-shaped outline said end being;` disposed within the turned over pon, tion of lthe atoresaidplate 60 the saidend engaging the inside of the paper asfitfis incident. with Ythe. width ot' the` paper or 30 Y being acted upon by the part- 60" of plate (SO.

The paper after the folding is completed passes 'between the feed rollers, alreadyY described, Where it receives a final messing before passing*v to the cuttinn knives.

The feed rolls to which reference has alreadyv been made are prefcrabl;7 n'iounted on spindles which inclined somewhat 'with regard to the center line of the paper, it has been found trat by so arranging' them, there is a slight tendenc,T for the paper to lift somewl'iat from the surface of the table facilitating; the feed of the paper to the cutting' knives.

in order to collect the cut paper a trayY may be provided, not shown, for which a support 62 may be arranged upon the pedestal of the table l.
